Entry title

  1. Protein extraction
    1. Cells were removed from freezer and warmed to room temperature in a water bath.
    2. Cells were sonicated
      1. Each vial was placed in an ice bath for 30 seconds
      2. Sonication device was placed in each vial for 30 seconds
      3. This was repeated 3 times for each vial.
    3. Cells were centrifuged at 18000rpm and 4°C for 2 hours to seperate ADA from E. Coli
    4. Binding and elution buffers were purified via vacuum filtration and a 450nm membrane filter.
    5. Vacuum filtration was used to seperate proteins from cells. ADA was collected in falcon vials and refridgerated.
  1. Solutions of Au/BSA at a mole ratio of 70 (at which fibers are not produced) with Tris at molarities of .05mM, .5mM, 5mM, 50mM, 100mM, 200mM, 500mM, and 1M went through two rounds each of UV/Vis.
    1. Stock solution for Tris was made
      1. 1mol/L *.025L = .025mol Tris
      2. .025mol * 121.14g/mol = 3.0285g Tris
    2. The equation M1V1=M2V2 was used to calculate the amount of stock and water needed in the 100mM, 200mM, 500mM and 1M tubes. A serial dilution was done from 500mM to .05mM to fill the rest of the tubes. 1mL from each tube was moved to the next with a pipette.
